Detailed Description

Light weight base class for most itk classes.

LightObject is the highest level base class for most itk objects. It implements reference counting and the API for object printing. It can be used as a lightweight base class in preference to Object. (LightObject does not support callbacks or modified time as Object does.) All ITK objects should be a subclass of LightObject or Object with few exceptions (due to performance concerns).

Member Function Documentation

void itk::LightObject::BreakOnError ( ) [static]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

virtual void itk::LightObject::Delete ( ) [virtual]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

virtual const char* itk::LightObject::GetNameOfClass ( ) const [inline, virtual]

Return the name of this class as a string. Used by the object factory (implemented in New()) to instantiate objects of a named type. Also used for debugging and other output information.
Definition at line 68 of file itkLightObject.h.

virtual int itk::LightObject::GetReferenceCount ( ) const [inline, virtual]

Gets the reference count on this object.
Definition at line 94 of file itkLightObject.h.

void itk::LightObject::Print ( std::ostream & os ) const

Cause the object to print itself out.

virtual void itk::LightObject::PrintHeader ( std::ostream & os,

Indent indent

) const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

virtual void itk::LightObject::PrintTrailer ( std::ostream & os,

Indent indent

) const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

virtual void itk::LightObject::Register ( ) const [virtual]

Increase the reference count (mark as used by another object).
Reimplemented in itk::Object.

virtual void itk::LightObject::SetReferenceCount ( int ) [virtual]

Sets the reference count on this object. This is a dangerous method, use it with care.
Reimplemented in itk::Object.

virtual void itk::LightObject::UnRegister ( ) const [virtual]

Decrease the reference count (release by another object).
Reimplemented in itk::Object.

Member Data Documentation

int itk::LightObject::m_ReferenceCount [protected]

Number of uses of this object by other objects.

SimpleFastMutexLock itk::LightObject::m_ReferenceCountLock [protected]

Mutex lock to protect modification to the reference count
